Hi all, Having problems adding values pulled from a string. I keep getting negative total when there are no negative numbers found in the file. I am sure it has something to do with my use of sprintf. Can someone take a peek at my code and advise where I am going wrong. Much thanks!!! 

open(IN,"$inFile");

while(defined($line = (<IN>))){
  $key=substr($line,34,1);
  if($key eq "7"){
   $VAL1 = substr($line,137,13);
   $VAL2 = substr($line,124,13);
   $VAL3 = substr($line,56,15);
   $TOT1 = sprintf '%020d',$TOT1+$VAL1    ;
   $TOT2 = sprintf '%020d',$TOT2+$VAL2    ;
   $TOT3 = sprintf '%020d',$TOT3+$VAL3    ;
    #print "$key \n";
   }
  if($key eq "8"){
   $VAL4 = substr($line,43,13);
   $VAL5 = substr($line,124,13);
   $VAL6 = substr($line,56,15);     
   $TOT4 = sprintf '%020d',$TOT4+$VAL4    ;
   $TOT5 = sprintf '%020d',$TOT5+$VAL5    ;
   $TOT6 = sprintf '%020d',$TOT6+$VAL6    ;
   #print "$key \n";
  }

   $TOT1 = sprintf '%020s',0 if ($TOT1 eq "");    
   $TOT2 = sprintf '%020s',0 if ($TOT2 eq "");    
   $TOT3 = sprintf '%020s',0 if ($TOT3 eq "");
   $TOT3 = sprintf '%020s',0 if ($TOT4 eq "");    
   $TOT4 = sprintf '%020s',0 if ($TOT5 eq "");    
   $TOT5 = sprintf '%020s',0 if ($TOT6 eq "");
